Life on other planets?

Question

If you believe there are life on other planets,do you think there are humanoid or another type of life form?

Answer 1

Probably not humanoid.

Answer 2

Of course there is. It actually is ignorant if someone thinks we, human are the only life-form in the universe.

Think about it. Human have evolved since some million years ago. And I think it's pretty safe to say that we were not looking like what we are now back then. We started from some simple cell organisms. With the help of the sun (right temperature) and air, we evolved to today as humanoid.

Sun and air are the major components for life-form. As we all know, there are more than one Sun in the Universe and there are more than one Universe in the "bigger-universe" (>.<)

The Chance of getting a planet with the right temperature from their suns and air is actually really big.

So yes. There are humanoid or definitely another type of life form on other planets.

The only questions would be,

1) Which planets?
2) Do they have the technology to transport all the way from their planets to earth?
3) They are not necessary any smarter than us, right?


Interesting question

Answer 3

I am amazed that there is life on earth! I have studied the mass extinctions of the end of Permian period, and several others. You had heavy vulcanism that filled the atmosphere with toxic gases and greenhouse gases.

The evolution of life on earth is rather circuitous. Earth is about 4.5 billion years old, but the oldest rocks appeared 3.8 billion years ago (before that you had a molten mess). Surprisingly quickly after the earth cool, about 3.5 billion years ago, life in the form of cyanobacteria evolved. At the begining, the "air" was poisonous (to us) consisting of methane and ammonia gases. Practically no oxygen. It took these bacteria over 2 billion years just to get the oxygen content to to few percent. It was not until 500 million years ago that something miraculous happened. During the Cambrian period multicellular life forms of many types started to appear.

How we went from one group of life form (chordatas) among dozens of wildly different ones to becoming hominids is rather fascinating. It was a tortuous path.

I believe that other life exists in this universe, just by the fact that it appeared on Earth so quickly. Whether there are other sentient humanoids? It is possible given the number of planets in the universe. Whether they near us, I would guess not likely.

Answer 4

If you accept the fact that the universe is infinite, then there must be an infinite number of stars out of an infinite number of stars there is a high probability of planets forming around those stars that would have the same circumstances occur that sparked life on our planet now just because we are carbon based life forms doesn't mean that other elements might be the predominate on some of these planets. Now a life form based on let's say silicon would of course develop differently in order to evolve to its surroundings just as "Humans" evolved the way they did in response to their surroundings.

Even if you believe in singular design you would have to accept the fact that any Deity that professes to love life would not put all his eggs in one basket and might decide to experiment with other forms of life in the infinite universe he created, otherwise why create such a large area.

Answer 5

after the discovered of how many more planets we now know are out there, the possiblity is very high that there is other life on other planets besides this one! (probably not humanoid - maybe even nothing but single sell organisms, but something!)

Answer 6

Most of the life on this planet is not humanoid. I'm inclined to believe that there are intelligent humanoids out there, but that they (we!) are greatly outnumbered by intelligent non-humanoids and also by non-intelligent humanoids. And all three combined are greatly outnumbered by non-intelligent non-humanoids.

Answer 7

They would most likely have a form that would be created by the life-giving elements of their planets, such as water, oxygen and climate conditions. One-celled organisms, perhaps, or multi-celled organisms that could or could not be humanoid.

Answer 8

Yes

Considering the series of flukes and mass extintions that lead to the final figure of mankind, humanoid or even vaguely human looking is VERY unlikely.

But since alien life has approximately 10 Billion years to develop, assuming even one of them established artificial intelligence technology, some kind of robotic life should be lurking and exploring somewhere in our galaxy.

otherwise, i doubt we will ever discover sentient life, but simpler life forms are probable on numerous albethey very far removed worlds from us.

Answer 9

I wouldn't doubt there is like bacteria on other planets but as for humanoids with bilateral symmetry and a developed brain i would say most likely not.

Answer 10

i bet its some other life form. We are how we are because of all the characteristics of earth. In order for it to be humanoids their planet would have to be exactly the same distance from the sun as us, rotate on exactly the same angled axis as us, revolve around the sun at the same rate and distance, etc... and their sun and planet would have to be the exact same age as ours. and a bunch of other exact specifications.

Answer 11

In a universe of infinate possibility, it's almost completely impossible they'd be humanoid, pretty likely we'd not recognise it as being anything like life on earth, and almost certainly single celled or very very basic, as something like 98% of the species on earth are single celled.
